How can I implement memory management to optimize and conserve memory usage?
Hello, I am developing an embedded Linux system with limited resources, powered by a 1 GHz ARM Cortex-A7 CPU and 256 MB of RAM. The end application is a real-time data acquisition and processing device for environmental monitoring. How can I implement memory management to optimize and conserve memory usage in this project? I recently came across the jemalloc library but don't fully understand it. Are there alternative solutions or libraries that would be more suitable for this application? I would also appreciate any information on the specific SoC or build system that should be used for building the embedded Linux.

Yes, these are standard authentication methods you can use to ensure secure communication and device identity in your IoT device.
X.509 Certificates, Pre-Shared Keys (PSK), OAuth 2.0, JSON Web Tokens (JWT).
The choice of method thuo depends on your specific requirements and the capabilities of your IoT devices and services.
@Enthernet Code For your memory management in your embedded Linux system with limited resources, you can look at the following steps, you can Optimize code for efficiency, in the same vein you can also prefer static allocation over dynamic, you can also Consider custom memory allocation routines, making Use of memory pools for fixed-size blocks is also insightful while aligning memory allocations for speed.
For real-time needs, you can also consider an RTOS. For SoC and build system you can choose a well-supported SoC, while using a lightweight build system like Buildroot or Yocto.
